This works around a known issue in ASan. ASan doesn't instrument weak symbols. Because instrumentation increases object size, the binary can end up with two versions of the same object, one instrumented and one not instrumented, with different sizes, which ASan will report as an ODR violation. In libc++, this affects typeinfo for `std::bad_function_call` which is emitted as a weak symbol in the test executable and as a strong symbol in the shared library. The main open issue for ASan appears to be https://github.com/google/sanitizers/issues/1017. Differential Revision: https://reviews.llvm.org/D119410
